[Bf-committers] Leap Motion Integration

[Hugo Lamarche]

Hi Ton,

Thank you for your welcome,

First just wanna clarify a little thing :

I am not from Leap Motion and actually I would like to ... ;-).

Then I am not realy confortable with license consideration but what I can
tell you is there is actually a python wrapper inside the Leap Motion SDK
for python 2.7.0 but they explain with this tutorial how to make it for
python 3.3.0. So if Blender use this kind of wrapper is there some problem
with the license problem ?

Or maybe we could factorize the connection to the Leap Controller with
the 3DConnexxion
?

For the support of blender, I think it could be interesting to use the leap
motion for different purpose :

- As a Constraint for animation record for exemple : like a follow path we
could have a follow hand.
- For sculpting / making pottery.
- As a 3d manipulator to quickly change object position / orientation /
scale
- And into the bge to get informations about hands / fingers as a python
module or / and sensors

Best

Hugo Lamarche
